What’s Medicaid?

Medicaid is a joint federal and state program that assists with medical costs for individuals with limited income and resources. It covers services not typically included in Medicare, such as nursing home care and personal care services. Eligibility varies by state, and some states allow a “spend down” of excess income to qualify.

Dual Eligibility

Medicare and Medicaid: If eligible for both, Medicare generally pays first for covered services, followed by Medicaid. Medicaid may cover some drugs not included under Medicare.

For more information:

• Visit Medicare.gov for details on plans, costs, and providers.
• Call 1800MEDICARE (18006334227) for personalized help.
• Contact your local State Health Insurance Assistance Program (SHIP) for free, local counseling.

Medicare vs. ACA Health Insurance Marketplace

If you have Affordable Care Act (ACA) Marketplace coverage, you should generally sign up for Medicare when first eligible to avoid coverage delays and potential penalties.

About ACA Marketplace Plans

The ACA or Obamacare, was introduced in 2008 to reform health insurance. It created Health Insurance Marketplaces to simplify coverage access and provide financial assistance.

ACA plans offer a variety of affordable options for millions, including those self-employed or between jobs.

Key Features:

• Marketplace: Enroll via HealthCare.gov or state-based platforms to compare insurance options.
• Pre-Existing Conditions: Coverage cannot be denied due to pre-existing conditions.
• Subsidies: Eligible individuals and families can receive tax credits to lower monthly premiums.

You can keep your Marketplace plan until Medicare starts. However, once you qualify for premium-free Part A or already have Part A, you may need to end your ACA coverage to avoid paying back subsidies.

•  Visit Medicare.gov
•  Read your “Medicare & You” handbook
•  Contact your State Health Insurance Assistance Program (SHIP)

Understanding Medicare Supplement Insurance (Medigap) 

Medicare Supplement Insurance,  commonly known as Medigap, is additional insurance offered by private companies designed to help cover out-of-pocket costs associated with Original Medicare. Here’s what you need to know:

 Coverage: Medigap helps with costs not covered by Original Medicare, such as:

•    Copayments
•    Coinsurance
•    Deductibles
•    Foreign travel emergency care (not covered by Original Medicare)

Explore our health insurance term glossary to better understand different costs. 

 Eligibility

To purchase a Medigap policy, you must:

•    Have Original Medicare (Part A and Part B)
•    Not be enrolled in Medicare Advantage Plans, Medicaid, or other types of health coverage like TRICARE or employer health plans

 Policy Features:

•    Standardization: Medigap policies are standardized and identified by letters (e.g., Plan A, Plan B, Plan C, etc.). All policies of the same letter provide the same basic benefits, regardless of the insurer.
•    Availability: There are ten Medigap plans available in most states, each with varying levels of coverage. Note that Plan C and Plan F are not available to new Medicare enrollees after January 1, 2020, due to changes in coverage for the Part B deductible.
•    Coverage Differences: Plans D and G offer different benefits depending on when they were purchased, and plans E, H, I, and J are no longer sold but can be kept if already held.

Buying Tips:

The optimal time to purchase a Medigap policy is during your Medigap Open Enrollment Period, which starts the first month you are 65 and enrolled in Medicare Part B. 

During this time, you can choose any Medigap policy without medical underwriting.

 Plan Pricing:

 Medigap policies are priced in different ways—community-rated, issue age-rated, or attained age-rated—which can impact your premium costs.

What’s Not Covered

Medigap does not cover:

•    Long-term care
•    Vision and dental care
•    Hearing aids and eyeglasses
•    Private duty nursing

Understanding Medicare Coverage and Costs 

Navigating Medicare can be complex, but understanding what’s covered and how much you might pay is essential for managing your healthcare expenses. Medicare generally covers services and items deemed “medically necessary” to treat diseases or conditions. Here’s a concise guide to help you understand what Medicare covers and your potential costs:

 What Medicare Covers:

•  Medically Necessary services include hospital stays, surgeries, lab tests, and doctor visits.
•  Medically Necessary items include durable medical equipment like wheelchairs and walkers.

 Factors Affecting Coverage:

•  Federal laws define Medicare benefits, while state laws may dictate what services providers can offer.
•  National Coverage Determinations: Medicare establishes national coverage for specific items and services.
• Local Coverage Determinations  Local companies process Medicare claims and decide if services are covered in specific areas.
• Specific Conditions: Some services or items may only be covered in certain settings or if specific conditions are met. For instance, organ transplants must be done in approved hospitals.

 Finding Coverage Information:

• Discuss with your healthcare provider about the necessity of services or items and whether Medicare will cover them.
• Visit Medicare.gov/coverage: Check if specific tests, items, or services are covered.
• Review the “Medicare & You” Handbook which provides information on coverage under Medicare Part A (hospital insurance) and Part B (medical insurance), including costs and benefits.
• Call Medicare: Reach out to 1800-MEDICARE (18006334227) for assistance. TTY users can call 18774862048.

Estimating Surgery Costs:

• Procedure Price Lookup: Use Medicare.gov/procedurepricelookup
•  to estimate costs.
• Consult Healthcare Providers: Ask about the costs of the procedure and any additional care needed.
• Check Your Medicare Summary Notice: Review whether you’ve met Part A or B deductibles and potential copayments.
• Verify with Other Insurance: If you have additional insurance like Medigap or Medicaid, check their coverage.

Reducing Your Costs:

Ask About Assignment: Ensure your provider accepts assignment to cover the Medicare-approved amount.

 Explore Assistance Programs: Look into programs for financial assistance if you have limited income. Check the “Medicare & You” handbook or Medicare.gov.

By staying informed and proactive, you can better manage your Medicare coverage and associated costs. For further information, always refer to official Medicare resources or contact Medicare directly.

New Medicare Changes You Should Know

Medicare is continually evolving to enhance accessibility and affordability for its beneficiaries. Here are some key updates that aim to make managing your health easier and more cost-effective.

Savings on Prescription Drugs: 

If you reach the catastrophic coverage phase with Medicare drug coverage (Part D), you will no longer be required to pay copayments or coinsurance. 

The Extra Help program has been expanded to provide greater coverage for individuals with limited resources and income. 

For certain Part B-covered drugs, coinsurance amounts may decrease if the drug’s price increase surpasses the inflation rate.

Reduced Costs for Insulin and Vaccines:

Insulin products covered under Part D will cost no more than $35 per month, with no deductible required.

Insulin used in traditional pumps covered under Medicare’s durable medical equipment benefit will also cost no more than $35 per month, with the deductible waived.

Recommended adult vaccines are now available at no cost to you.

Telehealth Coverage Adjustments:

Telehealth services remain accessible from any location in the U.S., including your home, through the end of 2024. After this period, most telehealth services will require you to be at a medical facility located in a rural area, though exceptions exist for mental health services.

Chronic Pain Management:

 Medicare will now cover monthly services for treating chronic pain if you have been suffering from it for more than three months.

Enhanced Mental Healthcare:

Coverage has expanded to include intensive outpatient program services provided by hospitals, community mental health centers, and other facilities.

More Enrollment Opportunities:

 If you are losing Medicaid or facing other specific situations, you may have additional opportunities to sign up for or modify your Medicare coverage.

Ongoing COVID19 Support:

Medicare continues to cover the COVID-19 vaccine along with various tests and treatments to safeguard your health.

For detailed information, refer to the specific pages mentioned in your Medicare handbook.
